there's the i-phone on the corner of davis and jackson streets. lisa drives to the spot and uses another i-phone to track down our thief. >> they are at the edge of the park. >> the map shows the phone inside the green area. >> it's right there. >> lisa heads for the park, but our thieves aren't there. >> so if we are here. >> maybe she's reading the map wrong? she gets help from a friend. >> they are on that side, right? >> yeah. >> so -- >> this is jackson. >> okay. >> now she thinks she's got them cornered. >> they should be right on this edge over here. >> lisa goes to the other end of the park. however, our thieves are not there either. >> they should be on davis and jackson, which is exactly where we are. and i was thinking they would be standing right there, but i don't see them. >> now she hits the button that makes the alarm go off from the stolen phone. however, she didn't hear any alarm. finally we get a little hint. the thieves are inside a coffee shop. now she's getting warm. she hits the alarm button again and this time it is heard.
